项目摘要

There are two formats of Internet-based lectures: real-time synchronous formats and asynchronous formats using VOD etc. In real-time interactive lectures, student-teacher communication is guaranteed, but of the two advantages of distance lectures, namely temporal and spatial degrees of freedom, temporal freedom is restricted. In contrast, asynchronous formats have high temporal and spatial degrees of freedom, but incur the problem of a lack of student-teacher or student-student communication. The aim of this research, therefore, was to develop a system that would support communication while maintaining the dual advantages of temporal and spatial freedom. Over a three-year period, a system with the following functions was developed.(1) A function that achieves virtual group learning where students not studying at the same time are able to share questions and answers as they work their way through the e-Learning System teaching materials.(2) A bulletin board system that automatically searches for similar past questions and answers in order to provide speedy response required when doubts arise in an e-Learning setting.(3) A blog function that encourages information-sharing (simple Trackback, similar note posting)(4) A function for expressing emotions/feelings during study time on the e-Learning System.(5) A video search function and partial audio support function to search for specific lecture scenes.(6) A function that allows students to see the progress of other students and a (student) peer-evaluation function.(7) A skill map to enable objective evaluation of young technicians' skills by veteran technicians in an in-house training system and a map-based objective test function.Medium- to long-term testing of the system showed it to be effective. Based on a major finding of the research, namely "a methodology for establishing interactivity even in an asynchronous system", further required functions will be identified and installed into the system.

基于Internet的讲座有两种形式：实时同步形式和VOD等异步形式。在实时交互式讲座中，师生交流是有保证的，但远程讲座的时间自由度和空间自由度这两大优势中，时间自由度受到限制。相比之下，异步格式具有较高的时间和空间自由度，但会导致缺乏学生与教师或学生与学生之间的交流的问题。因此，本研究的目的是开发一个系统，支持通信，同时保持时间和空间自由的双重优势。在三年时间里，开发了一个具有以下功能的系统。(1)一种实现虚拟小组学习的功能，在这种功能中，没有同时学习的学生能够在学习电子学习系统教材的过程中分享问题和答案。(2)一个公告板系统，自动搜索类似的过去的问题和答案，以便在电子学习设置中出现疑问时提供所需的快速响应。(3)鼓励信息共享的博客功能（简单的Trackback，类似的笔记发布）（4）在电子学习系统上学习时表达情绪/感受的功能。(5)视频搜索功能和部分音频支持功能，用于搜索特定的演讲场景。(6)允许学生查看其他学生进度的功能和（学生）同行评估功能。(7)一个技能图，使资深技术人员能够在内部培训系统中对年轻技术人员的技能进行客观评价，并具有基于地图的客观测试功能。根据这项研究的一项主要发现，即“一种即使在异步系统中也能建立互动性的方法”，将确定进一步所需的功能并将其安装到系统中。
